| 20090121473 | Optical Structure, in Particular for a Security Document and/or a Document of Value - The present invention provides an optical structure, in particular for a security document and/or a document of value, the structure comprising:
| 05-14-2009 |
| 20090186205 | MATERIAL IN SHEET FORM HAVING A WINDOW, ITS MANUFACTURING METHOD AND SECURITY DOCUMENT COMPRISING IT - The present invention relates to a material in sheet form comprising at least two fibrous jets juxtaposed on each other, a first jet comprising at least one long area of zero thickness and a second jet comprising at least one aperture, and said at least one aperture of the second jet being located facing the said at least one long area of zero thickness of the first jet, thus forming a window. | 07-23-2009 |
| 20090242153 | PROCESS FOR MANUFACTURING A FIBROUS PLY COMPRISING AN ELEMENT OF A GIVEN THICKNESS AND FORMING FABRIC FOR PRODUCING THE FIBROUS PLY - A wet process for manufacturing a fibrous ply on a forming fabric of a paper machine, including a stack of fabrics, the stack of fabrics having a surface fabric and at least one under-fabric, these being superposed, the fibrous ply having at least one element of a given thickness, wherein it includes the following step: formation of the ply by the dewatering of an aqueous fiber-based suspension on the forming fabric, the stack of fabrics of which includes a reduced dewatering region compared with the first under-fabric, in at least one under-fabric and/or beneath the surface fabric, the reduced dewatering region being in correspondence with the position that the element will have. | 10-01-2009 |
| 20090243278 | SECURITY STRUCTURE, PARTICULARLY FOR A SECURITY DOCUMENT AND/OR A VALUABLE DOCUMENT - The present invention concerns a security structure intended to be at least partially incorporated into or affixed to an article, particularly a security document and/or a valuable document, the structure comprising a substrate, at least one electronic device carried by the substrate, at least one non-electronic security and/or decorative element visible to the naked eye, carried by the substrate, covering only a portion of one side of the substrate and having no effect on the operation of the electronic device, and/or at least one amplifying antenna coupled with the electronic device and carried by the substrate, electronic device being at least partially visible so as to form with the security and/or decorative element a design chosen from among a geometric shape, particularly an ellipse, circle or polygon, a written symbol, particularly an alphanumeric character, and an image of a recognizable object, particularly a logo, a plant, an animal or a person. | 10-01-2009 |
| 20100181036 | PROCESS FOR MANUFACTURING A SHEET MATERIAL - A process for manufacturing a sheet material comprising at least two fibrous plies juxtaposed one on top of the other, including the following steps: a first paper ply is produced by filtration of an aqueous suspension of fibers on the wire of a cylinder mould or of a former; a second paper ply is produced on the wire of a second cylinder mould so as to form at least one recess in the second ply; at least one at least partially transparent element is placed between the two plies that are still wet; and the two plies are joined together so that said at least one recess of the second ply, the at least one at least partially transparent element and the at least one elongate region of zero thickness of the first ply are situated facing one another; then drying the obtained structure. | 07-22-2010 |
| 20100207377 | PROCESS FOR MANUFACTURING A SHEET MATERIAL - A process for manufacturing a sheet material comprising at least two fibrous plies juxtaposed one on top of the other, including the following steps: a first paper ply is produced by filtration of an aqueous suspension of fibers on the wire of a cylinder mould or of a former, a partly transparent element being inserted into the ply during the formation of the ply, and such that the transparent element is placed in the elongate region of zero thickness; a second paper ply is produced on the wire of a second cylinder mould so as to form at least one recess in the second ply; the two plies are joined together so that at least one recess in the second ply is located facing the elongate region of zero thickness of the first ply; and the structure thus obtained is dried. | 08-19-2010 |
| 20100264642 | SECURITY SHEET COMPRISING A FIBER SUBSTRATE INCLUDING AT LEAST ONE WATERMARK - A sheet including a fiber substrate including at least one watermark and having at least partially incorporated therein a ribbon that is narrower than the substrate and that overlies the watermark in part. | 10-21-2010 |
| 20100276488 | SECURITY STRUCTURE INCLUDING NEMATIC LIQUID CRYSTALS - A security structure including: a first region that is at least partially reflective and of low opacity; a second region that is at least partially reflective and of higher opacity than the first region; and a layer of a coating presenting birefringence properties, covering the first and second regions, at least in part. | 11-04-2010 |
| 20100295289 | SECURITY ELEMENT COMPRISING A DISCERNIBLE DESIGN - The present invention concerns a flat safety element, comprising a support that contains, on at least one of its faces, a set of elementary characters, characterized in that said elementary characters are equipped with a variation in shape and/or density and/or size in such a manner as to ensure a detectable design is at least visible. | 11-25-2010 |
| 20100295291 | SHEET INCLUDING AT LEAST ONE WATERMARK OR PSEUDO-WATERMARK THAT IS OBSERVABLE FROM ONLY ONE FACE OF THE SHEET - The invention relates to a sheet having a recto face and a verso face together with at least one watermark or pseudo-watermark and such that at least part of said watermark or pseudo-watermark is observable in transmitted light from only one of the faces of said sheet. | 11-25-2010 |
| 20110142279 | SECURITY PAPER - A security paper comprising a fibrous substrate comprising a watermark having repeating motifs, and a security structure that does not completely cover the watermark and has at least one semi-reflective area which is superposed at least partly on the watermark; which paper on the one hand allows observation, through the semi-reflective area, at least partially, of one of the motifs, and on the other hand allows observation at least partially of another of said motifs in a region of the watermark that is not covered by the security structure. | 06-16-2011 |
